Battery capacity calculator — other battery parameters FAQs If you want to convert between amp-hours and watt-hours or find the C-rate of a battery, give this battery capacity calculator a try. It is a handy tool that helps you understand how much energy is stored in the battery that your smartphone or a drone runs on.
To measure a battery's capacity, use the following methods: Measure the time T it takes to discharge the battery to a certain voltage. Calculate the capacity in amp-hours: Q = I×T. Or: Calculate the capacity in watt-hours: Q = P×T. What is the C rating of a battery? The C rating determines the rate at which the battery discharges.
For example, if you have a 12-volt battery that can provide 1 amp of current for 3 hours, the capacity of the battery is: amp hours = 1 amps × 3 hours = 3 amp hours. We have already shown various methods explaining how to calculate amp hours (Ah). Let's now see the particular battery capacity formulae:
To calculate the run time of a battery, the following formula is used: Battery Capacity in mAh: The total charge the battery can hold, measured in milliampere-hours (mAh). Battery Voltage in V: The nominal voltage of the battery. Device Power Consumption in watts: The power consume by the device being power by the battery, measure in watts.
The relationship between Voltage (V), Battery Capacity, and Watt-hours (Wh) or Joules (J) can be described as follows: Battery Capacity (in Wh or J) = Voltage (in V) * Battery Capacity (in Ah) This equation calculates the energy capacity of a battery by multiplying its voltage by its capacity in ampere-hours.
The formula used is: batteryWh = (batteryCapacity * voltage) / 1000 Then it divides this energy by the power consumption of the device to estimate the running time: runningTime = (batteryWh * efficiency) / devicePower The calculator assumes a constant power consumption which may not be true for all devices. The efficiency value is an approximation.
